• University of Arizona researcher Dr. William Rathji says that after a study based on looking into garbage cans, the average family wastes at least $150 per year in food.

  "Homemakers go out of their way to save pennies at the store and then don't realize that waste of edible (可食用的) foods adds up much more at home," said Dr. Rathji. He was one of about 100 food experts who met in Boise for a conference on food waste and ways to prevent it. American families throw out between 8% and 20% of edible food at a cost of $4.5 billion per year. That's almost as much as the federal government spends every year for food stamps and child nutrition programs. He found that food items which are costly and in short supply tend to be wasted more. During the 1973 meat shortage, meat waste increased to 9%, compared with 3% in 1974 and 1975. Sugar and sugar products waste jumped to 19% in 1975, when sugar prices doubled from the previous year. Dr. Rathji theorizes that high prices force consumers to experiment, sometimes buy in large quantities. In the case of meat, sometimes low-priced cuts for unappetizing varieties are purchased, consumers then tend to waste more. His theory is that the more variety in food bought, the more wasted. Regular bread is wasted at about a 10% rate, but specialty breads and rolls are wasted at a 20% rate. If people are eating the same thing every day, they learn how to manage it. But if you're trying to pull something out of the cookbook every night, that's bound to be some waste. Another finding is that lower income families waste less food than middle and upper income families. And the study found that dog food, which accounts for 8% of a shopping cart, is rarely wasted. Fresh produce and frozen items are more likely to be wasted. The study also showed people with the most knowledge of safe, edible food waste the least. Much food is tossed out because a homemaker suspects it is spoiled when it is not. 1、Large quantities of food are thrown out because a homemaker____. A、thinks they are not delicious B、 says they taste bitter and hot C、thinks they smell bad D、 suspects they are spoiled when they are not 2、American families throw out between____of edible food every year. A、5%～8% B、 8%～10% C、 20%～28% D、8%～20% 3、When sugar prices doubled, waste of sugar____. A、went down B、went up C、stayed the same D、was cut in half 4、Which of the following statements is true？____ A、American housewives are not good homemakers. B、Upper-income families are more wasteful than lower-income ones. C、American families throw away almost as much food as they consume. D、Americans waste a great deal of dog food. 5、When do American families waste more food？____ A、When prices are high. B、When food is scarce. C、When they think it is spoiled. D、All of the above.

• Researchers who picked up and analyzed wild chimp droppings said on Thursday they had shown how the AIDS virus originated in wild apes in Cameroon and then spread in humans across Africa and eventually the world. Their study, published in the journal Science, supports other studies that suggest people somehow caught the deadly human immunodeficiency ,virus (HIV) from chimpanzees, perhaps by killing and eating them.

  "It says that the chimpanzee group that gave rise to HIV… this chimp community resides in Cameroon," said Beatrice Hahn of the University of Alabama, who led the study. "But that doesn’t mean the epidemic originated there because it didn’t," Hahn, who has been studying the genetic origin of HIV for years, said in a telephone interview. "We actually know where the epidemic took off. The epidemic took off in Kinshasa, in Brazzaville." Kinshasa is in the Democratic Republic Congo, formerly Zaire, and faces Brazzaville, in Congo, across the Congo River. Studies have traced HIV to a man who gave a blood sample in 1959 in Kinshasa, then called Leopoldville. Later analysis found the AIDS viros. In people, HIV leads to AIDS but chimps have a version called simian immune deficiency virus (SIV) that causes them no harm. Humans are the only animals naturally susceptible to HIV. AIDS was only identified 25 years ago. The virus now infects 40 million people around the world and has killed 25 million. Spread in blood, sexual contact and from mother to child during birth or breastfeeding, HIV has no cure and there is no vaccine, although drug cocktails can control it. And like so many new infections, AIDS appears to have been passed to humans from animals they slaughtered. SIV has been found in captive chimps but Hahn wanted to show it could be found in the wild too. Her international team got the cooperation of the government in Cameroon and they hired skilled trackers. "The chimps in that area are hunted. It’s certainly impossible to see them. It is hard to track them and find these materials," she said. But the trackers managed to collect 599 samples of droppings. Hahn’s lab found DNA, identified each individual chimp and then found evidence of the virus. "We went to 10 field sites and we found evidence of infection in five. We were able to identify a total of 16 infected chimps and, we were able to get viral sequences from all of them," Hahn said. Up to 35 percent of the apes in some communities were infected. Not only that, they could find different varieties, called clades, of the virus. "We found some of the clades were really, really very closely related to the human virus and others were not," she said. Chimps separated by a fiver were infected with different clades, Hahn said. And a river may have carded the virus into the human population. "So how do you get from southern Cameroon to the Democratic Republic of Congo？" Hahn asked. "Some human must have done so. There is a river that goes from that southeastern comer of Cameroon down to the Congo River." Ivory and hardwood traders used the Sangha River in the 1930s, when the original to-human transmission is believed to have happened. Haha’s study suggests the virus passed from chimpanzees to people more than once. "We don’t really know how these transmissions occurred," Hahn said. "We know that you don’t get it potting a chimp, or from a toilet seat, just like you can’t get HIV from a toilet seat. It requires exposure to infected blood and infected body fluids. So if you get bitten by an angry chimp while you are hunting it, which could do it." Hahn’s study only applies the H1V group M, which is the main strain of the virus responsible for the AIDS pandemic. "It’s quite possible that still other (chimpanzee SIV) lineages exist that could pose risks for human infection and prove problematic for HIV diagnostic and vaccines," her team wrote. According to Hahn, the H A．Cameroon. B．Kinshasa and Brazzaville. C．Congo River. D．Nile River.
